Specific Heat Of A Metal Lab Answer Key. Lab four 4 specific heat of a metal table 1 specific heat and density of selected metals element specific heat (cal/g °c) density (g/ml) aluminum 0.215 2.7 copper 0.092 8.9 iron 0.106 7.9 lead 0.038 11.4 magnesium 0.243 1.7 tin 0.052 7.3 zinc 0.093 7.1 brass 0.09 8.5 Specific heat is a physical property of matter similar to density.
Determination of specific heat of a metal. Calculate the specific heat of the unknown metal. Q m = m m c m δt c m = (q m) / (m m δt) c m = (1830.5) / (62.72 x 71.50) c m = 0.408 j/g o c.
Mass Of Metal Sample Unknown #1 Or Unknown #2?
Determine the specific heat of a metal, using a calorimeter and the specific heat of water. Up nhm lab technician cut off , answer key. You can then calculate the heat gained by the water, which should be equal to the heat lost by the metal.
You Will Then Set The Heat Lost By.
If the specific heat of an unknown metal is calculated, the identity of the unknown metal can be revealed. Known quantity of water in a calorimeter. Specific heat is a measure of the number of calories needed to raise 1 gram of that substance 1 degree.
A Speciﬁc Heat Of 4184J/Kg.
Therefore, specific heat of the metal (c m) is given by: The amount of heat gained by the water was calculated. You will then place it in cold water and monitor the temperature change.
Use Units To Set Up Your Calculation, And Label What You Are Calculating.
2) why is δt water > 0 ? Specific heat of a metal. Specific heat of brass = 0.405 j/g o c.
Add The Piece Of Metal, And Heat It Up On The Stove Or Over A Bunsen Burner.
At equilibrium the temperature of the water and metal was 33.5 °c. Show all calculations you need to do to determine the specific heat capacity. In this lab you will heat a metal and then transfer it to water and see how much the water changes in temperature.
